1.0 Overview of the DMC1500
The DMC1500 is versatile digital motor controller that allows motor controller designersexamine certain characteristics of the TMS320F240, TMS320F243, andTMS320LF2407 Digital Signal Processors (DSPs) to determine if one of these DSPsmeets their application requirements. Furthermore, the module is an excellent platformto develop and run motor control software for the TMS320F240, TMS320F243, orTMS320LF2407 processor.
The DMC1500 uses a F240, F243, LF2407 DSP Starter Kit (DSK) or eZdspTM LF2407board as the computer engine to run algorithms. The DMC1500 along with a DSK oreZdsp allows full speed verification of F24xx code.
Code development for the DMC can be done in two ways;
• Use the serial interface on the DMC with the symbolic assembler and
debugger that comes with the DSK, or JTAG Port on the eZdspTM LF2407.• Use the XDS510PP PLUS JTAG emulator from Spectrum Digital, with the compiler/assembler/linker and Code Composer from Texas Instruments.
Note: It is recommended to use the SPI110 Opto Pod during developmentfor safety from high voltages

The DMC1500 is the power stage of a Digital Motor Controller development system.The computing engine for the DMC1500 is either a F240 DSK (#701023), F243 DSK(#701024), or LF2407 DSK (#701025) from Spectrum Digital. The DMC1500 allowsdevelopment to be done with AC Induction, DC Brushless, and Switched Reluctancemotors. To accommodate these 3 types of motors, the DMC1500 has many jumperoptions and connections. Please be sure to read this entire manual before poweringup a motor.
A board outline of the DMC1500 is shown below.

2-4 DMC1500 Technical Reference
The DMC1500 is a stand alone module that is not enclosed. It is intended to be usedin a development environment only. High voltages are present on the DMC1500 alongwith components dissipating heat. The user is advised to use extreme caution.
2.2 Installation of the DSK on the Digital Motor Controller
The F240, F243, or LF2407 DSK is the computing engine of the DMC1500 system. The DSK must be installed on the DMC1500 by plugging the DSK into matingconnectors. There are two ways to develop and debug algorithms for the DMC1500:
• Use the serial interface on the DMC1500 with the symbolic assembler and debugger that comes with the DSK• Use the XDS510PP JTAG emulator and SPI110 Opto POD from Spectrum Digital, with the compiler/assembler/linker and Code Composer from Texas Instruments.
Software can be developed using the symbolic assembler and debugger includedwith the DSK. This allows the engineer to generate algorithms and load theminto the RAM memory on the DSK. The DSK communicates to the debugger on thehost PC via the serial port on the DMC1500. The serial port on the DMC1500 isoptically isolated because the DMC1500 is operating at a floating voltage level.
Using the XDS510PP JTAG emulator with the SPI110 allows the engineer to debugalgorithms with the JTAG interface on the DSK. The SPI110 optically isolates the JTAGinterface and is required because the DMC1500 is operating at a floating voltage level.
DANGER !
NOTE:Do NOT use the serial port on the DSK because it is not optically isolated !
NOTE:The SPI110 MUST be used with a JTAG emulator !

2.3 Connecting Motors to the Digital Motor Controller
The DMC1500 will support the development of algorithms for a variety of motors. Eachtype of motor requires a specific type of connection. These connections are discussedin the following sections.
2.3.1 WARNINGS
The DMC1500 is capable of driving high voltage medium current motors. It is designedfor bus voltages of up to 350 volts with currents up to 10 amps. There is an onboarddiode bridge and capacitor. The bus current can be derived from AC, or DC can bedirectly driven in. There are many warnings that should be observed when operatingwith high energy devices.
The user is reminded to remove all power to the unit, motors,and associated electronics when connecting/disconnecting
wires or connectors.
DANGER !
Warnin gs:1. Make sure the bus is discharged before operating on or connecting probes to the equipment. There is an LED that indicates the bus is charged. It should not be used to guarantee that the unit is safe to touch. You should verify that the bus is discharged by using a voltmeter across the bus connections.
2. The input power must be fused externally for safe operation. The fuse should be sized to the voltage and current requirements of the load. You must also guarantee that the unit will not be fused above the safe operating range of the inverter module.
3. If the motor is being used for regenerative braking it will source current back into the supply. This will raise the bus voltage. If this is the case then the user must put a voltage regulator across the Bus terminals to absorb this energy. If this is not done then the bus voltage may rise above the maximum voltage and destroy the inverter board.

2.4.21 P29, CAN Interface (Optically Coupled)
Connector P29 is a 4 pin female mini-DIN connector which provides a CAN interface tothe DMC1500. The CAN feature is only available when using the F243 or LF2407 DSK.The TMS320F240 DSP on the F240 DSK does not have a CAN controller.
Because this interface is optically isolated power must be provided by the interfaceplugged into P29. If JP28 is installed, then a regulated +5 volts must be providedbetween pins 4 and 3. If JP28 is not installed then unregulated power up to 12 voltscan be applied. JP29 is the 120 ohm termination for devices on the end of the CANbus.
Note: Because of the optocouplers the full bus speed might not be possible. Startwith lower baud rates to verify operation.

2.11 Power Factor Correction
The Power Factor Correction Logic consists of Inductor L1, Diode D1 transistor Q1,and driver U2. The PFC supports a boost configuration. Without PFC power caps C1and C2 charge only when the voltage of the mains is greater than the voltage on thecaps. This causes high main current for short periods of time. The PFC logic storesenergy in the inductor all though the 60Hz cycle and transfers it to the Caps. The inputcurrent is more uniform and matches the input waveform.
Transistor Q1 is turned on which creates a current path from the bridge through theinductor, transistor and back to the mains. The control algorithm then turns thetransistor off. The energy in the inductor then travels through diode D1 and chargesthe caps C1, and C2. The control algorithm uses one pwm channel to drive thetransistor and uses input voltage, inductor current, and capacitor voltage to control thePWM duty cycle.
Note: The DMC1500 is specified for half output power rating when using the powerfactor correction.
2.12 Emulation Logic
The DMC1500 contains an additional watchdog timer that disables the drivers if it isnot strobed every 225mS. The software to strobe the watchdog should be placed in anInterrupt Service Routine (ISR) or in the main loop if timeout can be guaranteed. Thislogic is useful for emulation. If the emulator stops, the commutation will stop and therotor will lock. Stopping the emulator will also stop the watchdog which will disable thedrivers preventing continuous rotor current. There are also two other modes. Withjumper JP27 in position 2-3 the watchdog logic is disabled. When jumper JP27 is inposition 1-2 then an I/O pin can be used to enable the drivers and disable thewatchdog. The watchdog strobe is on T1CMP/IOPB6 of the C242. The Enable signal ison TDIR/IOPB6. Refer to the signal mapping when using the F240, F243, or LF2407DSK.

2.13 External Driver Power
The high side drivers in U3-U5 are normally powered by the boot strap method. If youwant to have continuous gate drive voltage then you can apply 12-15VDC toconnectors P8-P10. Each of these three supplies must be isolated from each otherand ground.
2.14 Power Stage
The power stage is either configured for ACI/BLDC or SR from the factory. SpectrumDigital does not support making a conversion in the field and this would void thewarranty. Both configurations use 20Amp 400V high speed IGBT’s. The ACI/BLDCconfiguration uses jumpers JP1-JP3 to tie the high side transistor to the low sidetransistor. The motor phases are then connected to P1,P3,P5. The SR configurationuses six 8 amp steering diodes across the IGBT’s. In this configuration the motorphases are connected between the upper and lower transistors.

2.15 Phase Current
The DMC1500 supports reading the phase current in the lower transistor leg. This isthe most common configuration. The currents are measured across three .04 ohmresistors. These sense signal are then filtered for a 40Khz cutoff frequency, clampedto the rails and applied to the non inverting input to an opamp. For each input there isalso a jumper to apply an offset voltage. This allows unipolar or bipolar currentmeasurements. The gain of each amplifier can be adjusted from 10 to 111. Theexample below shows how to calibrate the gain and offset for the U channel.
First determine your maximum current. In our example we will allow plus and minus5 amps. The maximum voltage across the sense resistor would then be:
V = I x RV = 5.00 Amps x .04 OhmsV = .20 Volts
The next step is to calculate the gain. Because we are measuring a bipolar current,0 A/D volts corresponds to -5 Amps, 2.5 Volts for 0 Amps, and 5.0 Volts for +5 Amps.This example assumes 5 volts input on the A/D (on the LF2407 the max A/D voltage is3.3 volts)
Gain = Vout/VinGain = 2.5V/0.20VGain = 12.5
The next step is to adjust the gain for the channels. Install jumpers JP11, JP14, JP16for bipolar operation. Pick a reference voltage such that it will not be greater than 5volts when multiplied by the gain. We will pick a reference voltage of .1 which whenmultiplied by 12.5 meets our criteria. Measure the voltage at JP11 and adjust R17 for0.1 Volts. Next measure the output voltages at JP24 pin 1 and adjust R12 for 1.25volts. Repeat this procedure for the remaining two phases. The final step is to adjustthe offset voltage. This is done by measuring the output voltage on one of the channelsat JP11 and adjusting R17 until the voltage is 2.5 Volts.

2.16 Phase Voltage
The phase voltages are measured from the top transistor with respect to Bus-. Eachphase is divided by a resistive divider consisting of 400K and 4.99k. This gives adivision of 81. Each channel also contains a filter with a cutoff frequency of 3.2Khz.The gain of each channel can be adjusted between 1 and 10. In our example we willassume a maximum voltage of 160 volts.
Op-amp voltage = Phase Voltage / 81Op-amp voltage = 160V / 81Op-amp voltage = 1.97 Volts
The next step is to calculate the gain. In our case we want the 1.97 volts to correspondto 5.0 volts to the A/D. The gain would be:
Gain = A/D Volts / Op-amp VoltsGain = 5.0 volts / 1.97 VoltsGain = 2.6
To set the gain make sure there is 0 phase volts. To set phase U volts install jumperJP10. Next measure the voltage on JP10 and adjust R17 for .5 volts. This sets areference voltage we will use to set the gain. The output voltage will be:
Vout = Ref x gainVout = .5v x 2.6Vout = 1.3V
Now measure the voltage on JP24 pin 17 and adjust R11 for 1.3 volts. Repeat thisprocedure for each of the phases.
Note: Make sure the jumper is removed after each adjustment

2.17 Bus/PFC Current
The currents are measured across .04 ohm resistors. The Bus current resistor R6 isshunted with a jumper JP4 from the factory. You can either have bus currentmeasurements or phase current measurements but not both at the same time. Toenable the bus current measurement cut out jumper JP4. These sense signal are thenfiltered for a 40Khz cutoff frequency, clamped to the rails and applied to the noninverting input to an opamp. The gain of each amplifier can be adjusted from 10 to 111.The example below shows how to calibrate the gain for the bus current.
First determine your maximum current. In our example we will allow 5 amps. Themaximum voltage across the sense resistor would then be:
V = I x RV = 5.00 Amps x .04 OhmsV = .20 Volts
The next step is to calculate the gain.
Gain = Vout/VinGain = 5.0V/0.20VGain = 25
The next step to adjust the gain is to install jumper JP7. Pick a reference voltage suchthat the A/D voltage will not be greater than 5 volts when multiplied by the gain. We willpick a reference voltage of .1 volts which when multiplied by 25 meets our criteria.Measure the voltage at JP7 and adjust R17 for 0.1 Volts. Next measure the outputvoltages at JP24 pin 25 and adjust R9 for 2.5 Volts.
Note: Make sure the jumper is removed after each adjustment
